Don't mess with the IDF

The son of one of Hamas's founding members was a spy in the service of Israel for more than a decade, helping prevent dozens of Islamist suicide bombers from finding their targets, it emerged today.

Codenamed the Green Prince by Shin Bet, Israel's internal security service, Mosab Hassan Yousef, the son of Hamas co-founder Sheikh Hassan Yousef, supplied key intelligence on an almost daily basis from 1996 onwards and tracked down suicide bombers and their handlers from his fatherís organization, the daily Haaretz said.

Information he supplied led to the arrests of some of the most wanted men by Israeli forces, including Marwan Barghouti, a Fatah leader often tipped as a potential president who was convicted of masterminding terrorist attacks, and one of Hamas' top bomb-makers Abdullah Barghouti, who is no relation of the jailed Fatah chief.

Mr Yousef, a 32-year-old convert to Christianity who now lives in California, has revealed the intrigues of his years as a spy in a new book called Son of Hamas, much to the concern of Shin Bet, whose operations will be revealed in detail. While the revelations may give a boost to Israel's intelligence service, whose external counterpart Mossad is still grappling with the diplomatic fall-out of last month's Hamas assassination in Dubai, there will be concern that the account may give too many insights into the murky world of espionage.
